Dinghy or kayak to state-owned Hell’s Half Acre and stroll around the island – it is only about a quarter-mile walk (and involves some scrambling at a few points), but the views are magnificent. While you are at it, go for a swim off one of the sand beaches on the island. At low tide, many sand beaches are exposed on the ledges at the east end of Devil, which are fun to explore and swim off. Devil Island is private and does not allow landing on or hiking on unless previously invited by an owner.
There are Maine Island Trail Association campsites on Hell’s Half Acre and another on the unnamed rock off the east end of Devil.
It is only 2.5 miles to Stonington (you’ll see its loom at night), so if you have a fast tender and feel confident about your anchor and dinghy’s range, a visit for dinner or shopping is possible.
